"This just in,the renowned Goldilocks was spotted leaving the residents of The Bears. Let's see if I can get the info on her." He moves up to a officer. "Good day officer can you give me any info on the case." The officer shrugged his shoulders and said. "I don't have much to go with but here is what we do know, It appears that the famous Goldilocks was strolling in the woods when she came across this house. She then made a Inference (something you think about using your observations) on who lived here. She went to the door and knocked when no one answered she thought that something was wrong. So she slowly creaked the door open she was inside, then she made a Observation (something you can sense) there was three beds. So she thought to herself, can I make this into a experiment. So she then laid on the first bed she thought, this is a air-mattress,the second was a regular bed,and the third was a water bed. So she thought the different kinds of beds could be the Levels of IV(something that yu measure using the IV). She thought that if these are the levels of IV then what is the IV (independent variable or something you change on purpose)? She realized that the IV was type of bed. Knowing her Levels of IV and the IV she thought, what is the DV(dependent variableor the thing you measure in like how comfortable the bed is)? She clicked like a light switch she found out what the DV was, the amount of time slept in bed. She then needed a unit of measure( the thing you measure) in like how long the bears sleep on the bed.Now she needed a Constant or two. One was person sleeping in bed, and two length of bed. Now she was set BUT She needed a Purpose. She came up with, The purpose of this investigation is to determine the effect of the type of bed on the amount of time slept in that bed." He paused and said "If you want more information you must speak with The Bears yourself." We moved to the house and asked The Bears what happened. The papa bear said in a deep voice " We came home and this mystery stranger was in our house, we asked what she was doing in our house. She then said I was conducting a experiment on what bed you sleep in the most. We calmed down and said OK and she walked home. About 10 min. later you guys showed up." "That's the whole story for now we will contact you soon with more information. This is Jack The Rabbit with Animal News thanks for watching."
